I have a gridview with hyperlink if i click on hyperlink the values going to button of the gridview.
protected void gvDetails_RowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.DataItem != null)
{
// DataTable readDt = null;
List<String> rows = null;
//Fetching the List from Session Object
if (Session["ReadJobDetails"] != null)
{
rows = (List<String>)Session["ReadJobDetails"];
}
if (rows.Contains(DataBinder.Eval(e.Row.DataItem, "JobTitle").ToString()))
{
//since we used GridView level CSS class, individual CSS class is not applying, so added manually
//e.Row.BackColor = System.Drawing.Color.FromArgb(208, 217, 206);
e.Row.BackColor = System.Drawing.Color.Silver;
e.Row.ForeColor = System.Drawing.Color.White;
e.Row.Font.Bold = false;
}
else
{
e.Row.BackColor = System.Drawing.Color.FromArgb(247, 247, 247);
e.Row.ForeColor = System.Drawing.Color.Black;
e.Row.Font.Size = 9;

I've next code that handle fowFormatting my cells:
private void gridViewRaces_RowFormatting(object sender, RowFormattingEventArgs e)
{
foreach (var cellColumn in e.RowElement.Data.Cells)
{
var cellInfo = cellColumn as GridViewCellInfo;
if (cellInfo != null)
{
cellInfo.Style.DrawFill = true;
if (cellInfo.ColumnInfo.Name == "columnContactProducerName")
{
cellInfo.Style.DrawFill = true;
cellInfo.Style.BackColor = Color.Yellow;
}
else if (cellInfo.ColumnInfo.Name == "columnTransport")
{
cellInfo.Style.BackColor = Color.Yellow;
}
else
{
cellInfo.Style.BackColor = ColorTranslator.FromHtml((e.RowElement.Data.DataBoundItem as RaceForListDto).Color);
}
}
}
//e.RowElement.BackColor = ColorTranslator.FromHtml((e.RowElement.Data.DataBoundItem as RaceForListDto).Color);
}
but my cells aren't painting. How to paint some cells in rows on dataBinding?
It looks like the proper event to do this is ItemDataBound event. See here:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/appearance-and-styling/conditional-formatting
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
//Is it a GridDataItem
if (e.Item is GridDataItem)
{
//Get the instance of the right type
GridDataItem dataBoundItem = e.Item as GridDataItem;
//Check the formatting condition
if (int.Parse(dataBoundItem["Size"].Text) > 100)
{
dataBoundItem["Received"].ForeColor = Color.Red;
dataBoundItem["Received"].Font.Bold = true;
//Customize more...
}
}
}
Or event better is to use a custom CSS class so that you can later make changes without having to rebuild the project:
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e){
if (e.Item is GridDataItem)
{
GridDataItem dataItem = e.Item as GridDataItem;
if (dataItem["Country"].Text == "Mexico")
dataItem.CssClass = "MyMexicoRowClass";
}
}
I assigned radiobuttonlist items programatically. i want the radiobuttonlist items are checked/not if checked i want the checked item to compare with another value,if equal increment score else do nothing i have written a code,but while debugging even though i checked the item it is taking null value please help me..

{
if (crctans[(int)ViewState["index"]] == RadioButtonList1.SelectedItem.Text)
{
score = score + 1;
}
}
ViewState["index"] = (int)ViewState["index"] + 1;
if ((int)ViewState["index"] == 10)
{
Session["result"] = score;
}

I resolved my problem and it may help someone else so i am posting it.. i have written wrong line:- GridViewState.Visible = true; // i have commented this line and error gone
protected void GridViewState_RowCreated(object sender, GridViewRowEventArgs e)
{
GridViewState.Visible = true; // i have commented this line and error gone
}
Would someone who knows DeveExpess ASPxGridView take a look at this.
Is this the best/correct way to use the grid to edit a List?
I have an object of Type ItemModel and the code below is used to allow an ASP.NET Web Site user to do CRUD operations on list of ItemModels.
My problem is that it seems too complex and I suspect I am not taking good advantage of the Grid.
For simplicity, I have left the Database Access Code that will load and save the list of ItemModels.
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
BindGrid();
}
protected void OnRowInserting(object sender, ASPxDataInsertingEventArgs e)
{
IList<ItemModel> itemModels = CachedModels;
int lineID = 0;
if (itemModels .Count > 0)
{
lineID = itemModels[itemModels.Count - 1].LineID + 1;
}
ItemModel itemModel = new ItemModel()
{
, Code = e.NewValues["Code"] == null ? string.Empty : e.NewValues["Code"].ToString()
, Name = e.NewValues["Name"] == null ? string.Empty : e.NewValues["Name"].ToString()
, DateCreated = DateTime.Now
, DateUpdated = DateTime.Now
};
itemModels.Add(itemModel);
CachedModels = itemModels;
ASPxGridView aspxGridView = (ASPxGridView)sender;
aspxGridView.CancelEdit();
e.Cancel = true;
BindGrid();
}
protected void OnRowUpdating(object sender, ASPxDataUpdatingEventArgs e)
{
IList<ItemModel> itemModels = CachedModels;
int lineID = Convert.ToInt32(e.Keys[0].ToString());
ItemModel itemModel = null;
foreach (ItemModel model in itemModels)
{
if (model.LineID == lineID)
{
itemModel = model;
break;
}
}
if (itemModel != null)
{
itemModel.Code = e.NewValues["Code"] == null ? string.Empty : e.NewValues["Code"].ToString();
itemModel.Name = e.NewValues["Name"] == null ? string.Empty : e.NewValues["Name"].ToString();
containerItemModel.DateUpdated = DateTime.Now;
itemModels[lineID] = itemModel;
CachedModels = itemModels;
}
ASPxGridView aspxGridView = (ASPxGridView)sender;
aspxGridView.CancelEdit();
e.Cancel = true;
BindGrid();
}
protected void OnRowDeleting(object sender, ASPxDataDeletingEventArgs e)
{
IList<ItemModel> itemModels = CachedModels;
int lineID = Convert.ToInt32(e.Keys[0].ToString());
ItemModel itemModel = null;
foreach (ItemModel model in itemModels)
{
if (model.LineID == lineID)
{
itemModel = model;
break;
}
}
if (itemModel != null)
{
itemModels.Remove(itemModel);
CachedModels = itemModels;
}
ASPxGridView aspxGridView = (ASPxGridView)sender;
aspxGridView.CancelEdit();
e.Cancel = true;
BindGrid();
}
private void BindGrid()
{
grdItems.DataSource = CachedModels;
grdItems.DataBind();
}
private IList<ItemModel> CachedModels
{
get
{
List<ItemModel> models= (List<ItemModel>)Session["ItemModels"];
if (models == null)
{
models= new List<ItemModel>();
Session["ItemModels"] = models;
}
return models;
}
set
{
Session["ItemModels"] = value;
}
}
I believe your current code is quite correct.
Here is the suggested way from DX:
ASPxGridView - How to implement CRUD operations with a custom data source
I have to bind a Dropdownlist with coutries which should be grouped by region, I have found a sample code from the following link,
http://www.codeproject.com/KB/custom-controls/DropDownListOptionGroup.aspx?msg=3984074#xx3984074xx
I wanted the country list same as this. But problem is that I want to bind the dropdownlist from sql result. I have tried the following but didn't work,
ddlCountry.DataSource = CountryDtoCollection;
ddlCountry.DataBind();
ddlCountry.Attributes.Add("OptionGroup", "Region");
any one knows any solution for this.
you can write a custom server control and use the data source witch containing the text and region separated by | then split it when use.
[ToolboxData("<{0}:CustomDropDownList runat=server></{0}:CustomDropDownList>")]
public class CustomDropDownList : DropDownList
{
protected override void RenderContents(HtmlTextWriter writer)
{
if (this.Items.Count > 0)
{
bool selected = false;
bool optGroupStarted = false;
string lastOptionGroup = string.Empty;
for (int i = 0; i < this.Items.Count; i++)
{
ListItem item = this.Items[i];
if (item.Enabled)
{
if (lastOptionGroup != item.Text.Split("|")[1])
{
if (optGroupStarted)
{
writer.WriteEndTag("optgroup");
}
lastOptionGroup = item.Text.Split("|")[1];
writer.WriteBeginTag("optgroup");
writer.WriteAttribute("label", lastOptionGroup);
writer.Write('>');
writer.WriteLine();
optGroupStarted = true;
}
writer.WriteBeginTag("option");
if (item.Selected)
{
if (selected)
{
this.VerifyMultiSelect();
}
selected = true;
writer.WriteAttribute("selected", "selected");
}
writer.WriteAttribute("value", item.Value, true);
if (item.Attributes.Count > 0)
{
item.Attributes.Render(writer);
}
if (this.Page != null)
{
this.Page.ClientScript.RegisterForEventValidation(this.UniqueID, item.Value);
}
writer.Write('>');
HttpUtility.HtmlEncode(item.Text.Split("|")[0], writer);
writer.WriteEndTag("option");
writer.WriteLine();
}
}
if (optGroupStarted)
{
writer.WriteEndTag("optgroup");
}
}
}
}
